Title: Electric discharge machining method for extremely high purity silicon
Inventor: TOJO TETSUYA
IPC: B23H1/00
Filed: 1995-01-31
Abstract: PURPOSE: To facilitate the electric discharge machining of extremely high purity silicon functioning as an insulating material by electric discharge machining the extremely high purity silicon after heating it for giving conductivity to it. CONSTITUTION: The resistivity fo extremely high purity silicon at room temperature is 30Ω.cm, and when the silicon is gradually heated up to 250 deg.C, 300 deg.C, 350 deg.C, 400 deg.C and 450 deg.C, the resistivity severally becomes 4Ω.cm, 0.6Ω.cm, 0.43Ω.cm, 0.26Ω.cm and 0.09Ω.cm. Thus, the extremely high purity silicon can be electric discharge machined when heated to 250 deg.C, but when heated to high temperature more than 300 deg.C, the resistivity becomes lass than 1Ω.cm, and the electric discharge machining becomes easier. But since a temperature limit where heat resistance, insulating ability and viscosity required by electric discharge machining liquid can be maintained is 450 deg.C, the upper limit of heating temperature of the extremely high purity silicon is fixed at 450 deg.C.

Title: Switching method for address generation mode
Inventor: KONO SEIICHI
IPC: G06F9/32
Filed: 1992-02-21
Abstract: PURPOSE: To perform normal switching by prereading an instruction, which will be executed following an instruction for address generation mode switching, to hold it in a prefetch queue at the time of executing the instruction for address generation mode switching. CONSTITUTION: JMP +2 is executed to flash a prefetch queue 2A, and contents of a DRO register are temporarily transferred to an EDX register and are returned to the DRO register by execution of MOV DRO and EDX. An instruction prefetch unit 2 prereads an instruction to store it in a prefetch queue 2A in the middle or execution or these instructions MOV DRO and EDX. Since the instruction (JMP offset value, selector value)to be executed following instructions MOV CRO and EAX for mode switching is fetched in a prefetch queue 2A, the system is prevented from being hung or malfunctioning because of transfer of the control to an erroneous address just after mode switching.

Title: Method of protecting bearing for stand-by blower in blower apparatus
Inventor: KODAMA TASUKU
IPC: F04D29/04
Filed: 1981-03-11
Abstract: PURPOSE:To improve reliability of equipment by introducing a portion of gas flow generated in an operating blower into a stand-by blower to rotate the stand-by blower and protecting bearings for a stand-by blower with this rotation. CONSTITUTION:Most part of the gas flow generated in an operating blower 2 passes through a reverse-flow preventing mechanism 4B to be sent to some predetermined place. A portion of the gas flow is introduced to the upstream side of a stand-by blower 3 from the downstream side of the operating blower 2 through an air duct 5A and to the upstream side of the operating blower 2 from the downstream side of the stand-by blower 3 through an air duct 5B after passing through said blower 3. Thus, the introduction of a portion of gas flow into the stand-by blower 3 causes a predetermined slight forward rotation of the stand-by blower 3 which prevents bearings for the stand-by blower 3 from wear caused by slight vibration generated continuously on the same surface of the interior of the bearings, unifies the wear of the bearings and protects the bearings.

Title: Radiation thermometer
Inventor: IDE TOSHIHIKO
IPC: G01J5/60
Filed: 1980-03-19
Abstract: PURPOSE:To eliminate the influence of emissivity to measure the true surface temperature even for a general object, by providing a spectroscope which selects three or more spectral radiation energies, a detecting element, a logarithmic converter, amplifiers, an adder and subtractor, and so on. CONSTITUTION:Spectral radiation energies of three or more wavelengths are selected from the radiation energy flux from object 1 by spectroscope 3 and are converted to electric signals by detecting element 4. Outputs obtained by amplifying these signals with preamplifier 5 are subjected to logarithmic conversion by logarithmic converter 6 and are involved by all values except values, which include selected wavelengths themselves, out of values proportional to differences of these wavelengths by amplifiers 7-9. These outputs are added and subtracted by adder and subtractor 10 and are converted to reciprocals by reciprocal converter 11 to obtain true temperature T0 of object 1. For example, the reciprocal of ln[V(lambda1)<(lambda2-lambda3)> V(lambda3)<(lambda1-lambda2)>/V(lambda2)<(lambda1-lambda3)>]-C is operated on a basis of electric signal V(lambda1)- V(lambda3) concerning three wavelengths lambda1-lambda3.
